Notes/Domino 8.5.3 Fix Pack 4 is a scheduled Fix Pack of low-risk, high-impact fixes to help customers safely avoid known issues. IBM strongly recommends that customers running Notes/Domino 8.5.3 upgrade to this latest Fix Pack since it addresses a small percentage of defects that impact the broadest set of customers. Fix Packs are released periodically between Maintenance Releases to provide a greater level of stability for customer environments. They go through the same level of fix, regression and interoperability testing that occurs with Maintenance Releases. Fix Packs are always cumulative and contain all of the fixes from previous ones.

Notes/Domino 8.5.3 Fix Pack 4 addresses defects in both the Client and Server. All Fix Packs are language independent and may be applied on any language version of Notes/Domino 8.5.3.
NOTE: The installer for Domino Interim Fixes (hotfixes) built 9 July 2012 or later requires a Perl 5.6.0 or later distribution on Unix & Linux platforms. For details, see technote 1600910.

Deciding to upgrade
Customers unable to upgrade to later Releases should install Fix Packs to benefit from later fixes made to the product. By providing a small number of fixes, customers are able to accept fewer code changes with lower risk, allowing them to "patch" an older Maintenance Release until a more extensive upgrade to the current Release is possible.

However, while Fix Packs provide important fixes and IBM strongly recommends applying the latest Fix Pack available for a Maintenance Release, IBM still recommends that customers upgrade to the latest Release + Fix Pack combination to receive the broadest set of fixes available. You will receive more overall fixes with a later Release + Fix Pack than with a set of Fix Packs on top of an earlier Maintenance Release. For more information, see technote 1368141 - "Differences between Notes/Domino Maintenance Releases, Fix Packs and Upgrade Packs."
Fixes contained in this Fix Pack
A plus symbol (+) before the SPR number indicates a fix for a regression bug. A regression bug is an issue that was introduced in a Maintenance Release but did not exist in previous releases of that code stream. For example, a bug that appears in 8.5.3 but did not exist in 8.5.2 is a regression.
If an APAR exists for the corresponding SPR, the APAR number will appear in parentheses next to the SPR number. For example, SPR# nnnnnnnnnn (LO12345).

What follows is a subset of the most important issues addressed in this fix pack. For the full list of fixes, please visitthe fixes by release view forthe description of each fix in this Fix Pack, including platform specific information.
